T all whom it may concern:

Be it known that I, HEN RY R. Gnirrnlv, a citizen of the United States, and a res dent of Phoenixville, Chester county, Pennsylvania, have invented Improvements in Galculating or Computing Machines, ofwhich the following is L'S-])C1fi0fli.10l1.

The ObJQCi} of my invention is to provlde a machine or instrinnentality for automatinecessarvto make up any given ainount,

cally registeringor recording the different denominations of coin and paper money such, for instance, as the various sums to be paid employees in large establishments. I

An instrument or machine"embodying my invention is particularly applicable for use in making up pay-rolls, although it may be employed for other purposes where it is desired to know the least number of'pieces of money, whether bank notes or other forms of paper money'or coins of the various denominations, required to make up a large number of sums of varying amounts.

My invention may be embodied in apparatus of varied form, having manually op erated parts which control mechanism to. effect the registration of the necessary pieces oi. money, or these keys may operate switches move the registering mechanism.

In the accompanying drawings, I have controlling an electric circuit designed toshown a number of instrumentalities for car rying my invention into effect, in which:

Figure 1, 1s a front elevation, partly in section, of one form of denomination calculator made in accordance with my invention; Fig. 2, 1s a sectional view of the same taken'on the line a-a, Fig. 1; Fig. 3, is a sectional plan view of the right-hand side of the machine, taken on the line b?), Fig.

1; Figs. 4 to 13, inclusive, are diagrammatic machine embodying my invention, in which I employ fewer keys than that shown in the machine of Figs. 1, 2 and 3; Figs. 18, 19, 20, 21, 22, 23-, 24 and 25, are detail views of the same; Fig. 26, is a plan view of an electrically operated calculator; Fig.27, is a crosssectional view of the same taken 011 the lineh h, Fig. 26; Fig. 28, issRsectional elevavarious amounts.

is,an end elevation of said plate structure;

Fig. 36, is an enlarged view of a portion of the structure shown in Fig. 2, illustrating in greater detail one of the registers or recorders employed with my calculating machinei Fig. 37, is an elevation of one of the registers or recorders, partly in section on the line ;0-p,-Fig. 36; Figs. 38 and 39, are transverse sectionalyiews on the lines r-r and ss, respectively, of Fig. 37, and Fig. 40, is

a view similar to Fig. 37, showing. a form of recording register which may be employed in connection with my improved calculating machine.

. In Figs. 1, 2 and 3, of the drawings here;

with, 1 represents a casing having a stepped top 2, through which project vertically movable operating rods or bars 3 having keys or buttons 4: whereby they may be readily actuated by the fingers of the operator; such-rods being normally upheld by springs 5. The casing 1 is duplex inform, having ninety-nine keys at the right-hand side for use incalon ating the number of coins required, and

ninety-nine keys at the left-hand side for use'in calculating the number of pieces of paper currencyrequiied in making up the \Vithin the casing are a series of slidable members 6 supported at their edges by rollers-7, which edges are preferably stifi'ened by members 8 adapt to the grooves of said rollers. These slides may be in the form of solid plates, having rows of apertures 9 in both directions, ten

each way, making one hundred in alkalthongh'I may employgrids 6 formed of a series of rods spaced apart equidistantly and secured as; the members 8,,and such structure is shown in Fig. 14. These slides or grids are held in'the normally retracted position by means of springs 10, and are provided-at their forward ends with rack barsll disposed in engagement with .pin-

ions 12 of registering or recording devices 13 of any suitable character, of which there is one for eachslide.

The vertical rods 3 are disposed in the aperturest) of the slidable members or between the rods of the grids, and the keyed j on each side of the machine contain figures from one to ninety-nine, inclusive. Each of;

said bars carries one or more cams 15, as may be desired,'of varying width, which cams coact with the slidable members 6 or the grids 6, so that by pressing any one of the keys, one or more of said slides will be moved, and the fact of such movement, and its extent, will be recorded by the respective registering devices.

Each of the five slidable members 6 on the right-hand side of the machine represent one of the coins to be used in making up the desired amounts, and each of the slides on the left-hand side represent one of the denominations of aper money. The slides on the right-han side, starting from the bottom, represent, respectively, a penny,

a nickel, a dime; a quarter-dollar, and, a half-dollar. Those on the left-hand side,- starting from the bottom, represent, respec tively, a one-dollar note, a two-dollar note,

'a five-dollar note, a ten-dollar note, and

in Fig. 4, so arranged that when said key is pushed down 'the slidable member 6 controlling the registration of pennies will be moved forward one space to register one unit on its recording device, and whenthe pressure of the finger is removed, said key will be returned to the original position by its spring The two-cent rod is provided with a cam twice the width of the onecent rod, which serves to move the penny slide twice as far, or a distance sufiicient to cause the rack rod to move the pinion and register two units, and so on for the threeand four-cent keys. The rod from the fivecent key is provided with a cam of the smallest size to engage the slidable member controlling the registration of nickels, and when pressed down it will cause such memher to move a suflicient distance to register a single nickel. From six to nine cents, inclusive, the respective keys are supplied with cams to move the slidable members controlling the registration of nickels, and with corresponding cams to make the re- 'spective movements ofthe slidable member controlling the registration of pennies. The ten-cent key is provided with a cam opposite the slidable member controlling the registration of dimes and moves the same one space, and so on throu hout the rest of the machine; the several diagram views, Figs. 4 to 12, inclusive, being taken on the lines of the several keys and showing the cams carried by each rod containing the indicated amounts. Fig. 13 shows the first row of rods on the dollar side of the machine.

'Theleft-hand side of the machine is constructed and operated in precisely'the same manner, the 'one-dollar key moving the slidable member controlling the registration-of the number of single dollar bills desired, the two'dollar' key moving the slidable member controlling the-registration of the number of two-dollar bills desired, the three-dollar key moving th'eslidable members controlling the registration of both the oneand two-dol1ar'bills,;all of such members being moved one space. The four-dollar kc fects sufficient movement of the sli able member controlling registration of two-dol lar bills to indicate'two units, and the fivedollar key. moves the slidable member controlling registration of fivedollar bills one unit; each slide through its rack rod 11 communicating motion to 'the corresponding registering device and recording the motions made and consequently the number of bills required. j

To illustrate the Operation of my improved machine, what is the fewest number of bills and coins that will be required to make up the several amounts, $18.74, $39.42, and $11.16? The purpose of this machine is to automatically calculate this desired information. This is done by "pressing first the key 18 on the dollar side, and the key. H on the cent'side'; thenthe key 39 on the. dollar side, and-the' key 42 on the cent side, then the key I1 on the dollar side and the. key 16 onthe cent side, all of which operations will be record ed on the several registers, which-will then indicate as follows The first register on the dollar side, representing the twenty-dollar bills will show the unit 1; the second regis ter on the dollar side, representing the tendollar bills will show-the unit 3; the third five-dollar bills will showthe unit 2; the

fourth register on the dollar side, repre-.

senting the two-dollar bills'will show the unit- 3; the fifth register on the dollar side, representing the onedollar bills will show the unit 2. The first register on the cent side, representing the fifty-cent pieces will show the unit 1; the second register on the cent side, representing the twenty-five cent pieces will show the unit 1; the third register on the cent side, representing dimes will one-twenty dollar bill: three-ten to ascertain the fewest pieces of money in the total sum. but in the several sums aggregatlng such total whereby each of the smaller sums may he paid witht-he fewest pieces of money, and in this connection it is to be noted that neither the registers nor the recorders (it used) will showthe amount of money under consideration. On the cent side of the machine,'the cent register will indicate the number of pennies required in any given amount, or in the payment of any given centum amountspthe next register will indicate the number of five cent pieces;

the next the number of dimes: the next the number of twenty-five cent pieces or .quarters, and the next the number of fifty cent pieces or half dollars. 011 the dollar side, the same condition will exist; the first register indicating the number of one dollar bills, and consequently the same read off will be dollars; the next will indicate the number of two dollar bills. and in order to know the sum of money, it is necessary to multiply the amount indicated by 2: the third indicates the number of five dollar bills. and in order to ascertain the money involved, it is necessary to multiply the numbers on the register by 5; the next indie-ates the number of ten dollar bills involved, and to find out the sum of money,

it will be necessary to multiply such numher by 10, while the last register will show the number oftwenty dollar bills involved. and to ascertain the amount of money. it will be necessary to multiply such number by. 20. Each register, therefore. is termed a unit register or accumulator: that is to say, it registers certain units of value. The penny is a unit; the five cent piece is a unit; the dime is a unit: the twentyfive cent piece is a unit. and, the fifty cent piece is a unit, and such units will be indicated upon the different. registers as such; the object of. the whole invention beingto pro-.

vide mechanism that will separate the amounts represented on the indicators or keys into units representing. the fewest pieces ofmoney in said amounts. The a gregate of the units ofthe various registers,

recorders or .accumulators will show the number of pieces of money necessary to pay ofl the various sums' indicated by the vari ous keys pressed. This calculation is recorded by the instrument without any thought upon thepart of the operator, except to depress the keys indicatingthe amounts expressed in the account, or pay roll, of which the number of hills and coins are to be determined.

Although I have shown and described a series of slidable members for communicating the motion of the vertically moving rods to registering mechanism, I do not wish to be limited to such actuating mechanism, as the necessary motion may be communicated through rock shafts, by rotatingslides, or

use. Instead of employing the cams for effecting the movement of the slidable memhers, I may employ a direct connection, or use a leverforming a direct connection between the keys. 1

. In Figs. 14, 15'and 16, I show portions of a form of instrument in which the rack bars by any form of transmitting mechanism in 11 for transmitting movement-"to the recorders are carried by rods (3 which are actuated by levers 17fix'ed to cross bars 18, such. cross bars also having arms 19 to be moved by projections 15* carried by the rods 3 of the keys. The levers 17 and the arms 19 are fixed to the .cross bars and the latter are arranged torock in their hearings. In order to provide for the registry of more than one coin, as will be desired to record the necessary amounts, the projections 15 carried by the rods are disposed correspondingly nearer the leversQso that the full depression of the keys will, in some instances. effect 'a greater movement of the levers and in consequence a greater movement. of the ,rackbars. The general arrangement of the machine in all other respects is the same as that shown in Figs. '1, 2, 3, with the slidable members for actuating the recording mechanism; the cross bars 18 being arranged in tiers above each oth er. At the tiers where no coins of the particular value would ever be needed in making up any amounts. the bars 18 may be omitted.

Instead of amachine having ninety-nine keys on the dollar and ,ccnt aside, totaling. one hundred and ninety-eight keys in all, I show in Figs. 17. to 25, inclusive, the details of a machine in'whichonly thirtyeight keys are employed. Figul'f, is a perspective View of this thirty-eight-keyed ma-"' chine.

Fig. 18. is a plan view of the slidahle member 6 controlling the registration of units representing pennies of such'thirtyeight-keyed machine. in which twenty keys are provided for the denominations less than one dollar,'and eighteen keys for denominations of one dollar and over. This slidahle member 7 through which the rods 3 controlled hv keys is provided with openings 20,

pennies is operated directly, because in all amounts ending with one, two, three or four, the corresponding number of pennies is required.

Fig. 19, 1s side elevation of the unit rods on the cent side of the machine, showing also a sectional view of the penny slide. I provide cams 15 on the rods of. keys five 7, six, seven, eight and-nine, for engagement with the slidable member controlling the registration of quarter dollar 'co1ns, because.one of such coins is needed with all sums ranging from twenty-five to twenty-nine cents, and from seventyfive to seventy-nine cents. This slidable member cannot be operated directly by either rod of the two or the seven key in the tens column on the cent side-of the machine, on accountof .not needing one of these coins with sums ranging from twenty to twenty-four cents, or from seventy to seventy-four cents. .1 provide cams for engagement with the slidable member controlling the registration of dimes on all of the unit keys, because dimes are needed with all sums ranging from thirtyfive to forty-four cents,- and from eighty-five to ninety-four cents. The

registration of dimes is required with all the units. I also provide cams for engagement with the slidable member controlhng the registration of two dimes on all the unit rods, because two dimes are, needed with all sums rangin'gfrom twenty to twentyfour cents, forty-five to forty-nine cents, seventy to seventy-four cents,

and ninety-five to ninety-nine cents.

Two dimes are also needed with all the units. I provide cams for engagement with the slidable member controlling the registration of nickels on all of the keys of the unit column, becausenickels are needed with all sums ranging from five to nine cents, fifteen to nineteen cents. thirty to thirty-four cents, forty to fortytour cents, titty-five to fifty-nine cents, sixty-ive to sixty-nine cents, eighty to eiglityfo1i1" cents, and ninety to ninety-four cents. Nickels, therefore, are also needed with all of these units.

In Fig. '20, I have shown a plan view of the slidable member controlling the registration of nickels. The slidable member is provided with centrally disposed bars 25 and 26 mountedon both sides of the same, to which bars are pivoted arms 27 and 2S 'able member forcing t respectively. These arms extend laterally from said bars 25 and 26, and are coupled by bars 29, to which springs 30 are attached to hold the structure'in the normal position. The armsdo not touch the rods near to which they are disposed, so that if the nine key in the unit column was depressed, for example, it would simply rock the arms 27 on the upper side of the slide same on the tens side againstthe rods of the keys on that side just as it reached the end of its motion, without giving theslidtible member any forward movement. In the same way, if the naught key on the unit side. was depressed, it-wouldsimply rock the arms 28 on the under side of the slidable member. If the six key on the tens side was depressed, it would rock the arms 27 in a direction opposite to that produced by the nine. key in unit column, and if the 'four.key on the tens side were to be depressed, it would rock the arms 28 in the opposite direction to ,the movement produced by the naught key in the unit column. If keys nau ht, ten

slidable member, but simply a rocking movement of the arms 27, since there are no arms to be opposed by cams on the rods of keys naught, one two three and four. In the same manner, when keys thirty, forty, eighty or ninety in the tens column are depressed, together with keys naught, one, two three or four on the unit side, a forward movement of the sildable member would result through the locking of the arms 28, and depression of keys thirty, forty, eighty or ninety in the tens column with keys five six seven eight or nine in the unit column would simply impart rocking movement to the arms 28. That this is correct willbequite evident, as a nickel is needed with the sums of five, six seven, eight nine fifteen, sixteen, seventeen, eighteen, nineteen, thirty thirty one thirtytwo thirty-three, thirty-four, forty forty-one, forty-two, forty-three, forty-four, fifty-five, fifty-six, fitty-seven fifty-eight fifty-nine sixty-five sixty-six I sixty seven, sixty-eight. sixty-lime, eighty, eighty one, eighty two, e ghty three eighty-four, ninety n1nety-' one nmet -two,

ninety-four cents.

Fig. 9.1, isa side elevation of the tens rods 3 on the centside of thestructiire .for

moving the slidable members controlling the registrationot the various coins, showing also a sectional view of the nlckel shdable' member. The keys for the sums offifty sixty seventy, eighty and ninety cents, act directly on the slidable member 1 controlling the registration of fifty-cent pieces. The slidabl'einember for registering twenty-five cent coins is moved'by cams on the rods of the keys for the sums of thirty forty, eighty and ninety cents,

# which act directly on said slidable member andby cams on the rods of the keys forthe sums of twenty and seventy cents to act in combination with the rods of the keys for the sums of five siX seven eight and nine 'cen'ts'in the unit column. as will be pointed out hereinafter. The rods of the keys for the-sums of ten and sixty cents are also provided with cams which act directly upon the slidable member. controlling the registration of dimes, and the rods of the keys for the sums of thirty, forty eighty and ninety cents, have cams for operating the said slid able member, which-act in combination with'the cams for said member on the 5 thirty unit side of the machine. The rods of the keys for the sums of twenty, forty, seventy and ninety cents have cams for acting upon the slidable' member controlling the registration of two dimes, which only actin combination with cams on the rods in the unit column for engagement .with said Zslidable member. The rods of the keys for the sums of naught. ten LC 7P I 7 i 7 eighty and ninety cents, have cams for acting upon the slidable member controlling the registration of nickels, which act only in combination with rods in the unit column 59 having cams for engagement with the corresponding slidable member; the rods for the sums twenty and seventy having no cams in the tens colnmn, because there is house for a .nickel in any sums ranging from twenty -to twenty-nine cents, or

from f seventy to seventy-nine cents.

The slid able member for effecting the registration of dimes will be equipped with four sets of/swinging or rocking arms 35, 36,

3.7 and 38, of the same character as thearms 27 and 2S employed in connection with the slidable member for effecting registration of the nickels; 'two of said sets of arms being r on the upper side of said'slidable membei" and two on the under side. These arms are ninety-three and H :twenty-four cents, from forty-five'to '24., asection on line g-g of Fig. 22, showing forty-nine cents, from seventy to sevent T four cents and from ninetyfive to ninety-nine cents. For sums from ten to nineteen cents and from sixty to s1xty-nme cents, the operation of the dime slidable member will be-impart 1 ed directly by one of the operating rods.

In'Fi s. 22 to 25', inclusive, I hayte illustrated tie details of the dime shdeofthe 38-keyed machine. Fig. 22, is a plan; Fig.

'25, an end elevation; Fig. 23, a side elevation, showing the unit key rods, and Fig.

the'tens key rods. The arms 35, 36, 37 and 38' are secured in precisely the same manner as they-are secured to the slidablemember controlling the registration of nickels. The arms 35 are disposed just in front of .the thirty and eighty keys on the tens side, and just in front of the. five, six, 5

seven eight and nine keys on the unlts side. The arms36 are'dlsposed ust in front. of the forty and ninety keys on the tens side, and just in front of the f naught one two, three and four keys on the units side. Below the dime slidable member and at a suflicient distance therefrom to permit of the operation of the cams on the several keys, the swinging' arms 37 and 38 are mounted. The arms 37 are disposed just in front of the forty and ninety keys on the tens side, and in front of the live ,six,seven,eight and nine keys on the units side, and the arms 38 are disposed just in front of twenty and seventy keys on the tens- -side and in front otthe naught one two three and four keys-on the units side. These arms are so located in relation to the key rods-as to allow "plenty of room to swing without coming in contact with said rods. on the dime-slidable member, a wall 39 isdisposd in' front of the ten and sixty ke'ys'onfthe tens side. Each set of arms is provided with suitable springs in 'thesamemanner as the slidable member shown in Fig. 18; such springs being attached at their opposite ends to theslidable member. These springs are very light and week, not ofsuflicient resistance to 'cause any tendency of the slidable member to move forward against the resistance of recorders and the much heavier spring lO controlling the position of theslide. The purpose of these light springs is to cause the members to return to their normal position' when rocked or swung through the operation of a, combination of. keys which would produce such motion, and to prevent on the tens side, and keys five six,

the possibility 'of these members coming to -rest with any of their arms in contact with the key rods so'a's to be violently rotated when the key with which the might be in contact is depressed. I pro d e guides 40 for the arms 37 and 38 on the under side ofthe machine. These guides are fastened to the slidable membe and are provlded with slots ll in which said arms 37 and 38. .may move horizontally, but these slots prevent any vertical movement and relieve said arms from the torsional strain of the ver tical component of the thrust of said key rods. 4

The operationot the dime slide is as follows: If the naught key on tensside is depressed with any key on unit'side, it'will simply cause the arms 35 and 37 or 36. and 38 to swing from right to left. If keys ten and sixty are depressed, the slid able member would be moved forward one unit of distance by direct action on the wall 39, and the keys on units side would sim ply swing the arms 35, 36, 37 and 38, as before. Itthe twenty and seventy keys are depressed with keys five six, seven, eight or nine, the arms 85 and 37 will be caused to rotate, but is pressed with keys naught, one, two three or four a forward movement of the slidable member through two units of distance will be effected and two dimes will be recorded; this action being effected through the arms 38 at the same time the camson the keys naught one two three or four at the dime level would swing the arms 36. lVithout the necessity of going through a full description of the action of all the keys it is suflicient to say that swinging will take place where the arms in front of the cams on keys used are not on the same member, and a forward motion of shde will take place where the arms iii front of the two keys depressed'are on the same member; such motion being in proportion to pitch of the cams. The. naught and fifty keys will not give a dime with any of the units the ten and" sixty keys will give a dime by direct action no matter what units arepressed; the twenty and seventy keys will give two dimes with naught. one two three or four keys; the thirty and eighty keys will give one dime with five, six, seven eight or nine keys, and the forty and ninety keys will give one .dime with naught one, two three or four keys and two dimes with five, six seven, eight or nine keys.

On the slidable member controlling'the. reglstration of twenty-five cent pieces, there seven, eight and nine o1"1 the unit side; in order that a twenty-five-cent coin will be registered for all sums from twenty five to twenty-nine cents and from seventy-five to seventymine cents. Such coins as are needed with sums ranging from thirty to forty-nine cents and from eighty to ninety-nine cents will be registered directly by the action of the rods upon said slidable member. The halfdollar coins or fifty cent pieces are all obtained by direct action of the rods upon the slidable member controlling the registration of such coins.

I have only described the arrangement and action of the cent side of the thirtyeight-keyed machine, but it will be understood'that. the slidable members of the ddllar side are constructed and operated in the same manner as the slidable members of the cent side. 1

In Figs. 26 to 30, inclusive,.I- have shown a machine arranged toope'rate by the use of electric current, the contacts being made directly by the key rods 3 In the casing. of the machine a plate 45 formed of conducting material is mounted on insulating strips 46 of wood or other suitable material. This plate is provided witha binding post 47 and is perforated at 48 to guide the end of the key rods 1 Alternating layers of conducting and non-conducting material 49 and 50, respectively, are disposed within the casing, the layers of conducting material being positioned in the same manner and taking the place of the slidable members. The top and bottom pieces 50 of non-conducting material extend beyond the others to form means for fastening the structure to the casing of the machine; forinstance by the screws 51.. The members 49 may either be continuous perforated plates of the form shown in plan, Fig. '26, or they may be short sections connected by wires'or other contact means. \Vhat is desired is an electric conductor extending over the whole space occupied'by the key board. The members 49 are extended at one end as shown, and are provided with binding posts 51, 51,

51* 51" and ol The arra'n ement is such that the 1nembers'49 and 50 formvertical walls of-alternate strips ofconduct'ing and.

non-conducting material, and between these walls the key rods 3* pass. These key rods are supplied with springs 5 at their lower ends resting on the plate 45. The springs serve'the double purpose of returning the keys. to normalposition when released after being depressed, and of supplying a permanent electric connection between theplate 45. and the key rods 3 which'latterlnust be conductors. The rods 3 are supplied wlth contacts 52 as shown in Figs. 2-7 and 29; Fig. 27, being a section just in front of the line of keys controlling the registry of nickels, and Fig. 29, a section of part justin front of the naught line of keys. Fig. 29, shows just sufficient parts to illustrate the arrangement of contacts. Magnets 55, 55, 55 55 and 55, for the several layers of conducting material controllingthe recording of the cams with corresponding registering mechanism are shown, which magnets are fully described hereinafter.

The plate 45 is connected at one side to a suitable battery or other source of electric current, the other side of battery being connected to one pole of the several magnets.

are all'placed at the same distance above the center of the conducting plate with which they are tofo'rm contact, and this distance .is equal to the vertical distance through which thelkeys may be depressed. Therefore, except for. pennies and two dimes, the contacts will all pass to center of conducting plates and "return, thus making and break ing circuit once and therefore causing resigned to yieldtwo'dimes are placed at a distance above the conductors 49*,330 that the f depression of the key will cause contact to pass clear across and beyond 49, thus inakingand breaking the current once in' the descent and once in the ascent.' The onepenny ke'v, see Fig. 27, has one contact placed the full distance of movementof keys above center .of eonductor49; the two-penny key has one contact placed asfor two dimes, only being above conductor 49 instead'of conductor 49"; the three-penny key has two con-* tacts, one placed at-.the distance of move ment of keys ahove'center of conductor 49* and theother close to conductor 49, so that the lower one will reach and cross conductor 49* before the upper one reaches it; then the 'upper one will-reach. There will therefore bethree makes and breaks of current and a;

key rods hear one contact at the proper dis tanee of movement above conductor 49', the twenty key rods hear one contact at less than the distance of movement above conductor 49", the thirty key rods hear one contact at distance of movement above coiiductor 49", and another at distance .of movement above conductor 49*. The forty 7 key rods hear one at proper distance above conductors 49, 4.9 and i9, the fifty key rods 7 5 hear one at proper distanceabove conductor 49. The five key rod bears one contact at proper distance above conductor 42), the fifteen key rod' has contacts at proper distance above conductors 49 and 49, the

twenty-five key rod has contact at proper distance above conductor 49, the thirtyfive key rod has contacts at proper distance above conductors 49 and 49", the fortyfive key rod has one contact at proper distaiice above conductor49 and one at less than distance of movement above conductor 49 Above fi'ftyQthekey rods bear the "same contacts as below fiftv. with the fifty contact added. That is to say, key

rod fifty-five is the same as key rod five with fifty added; key rods eleven twelve, thirteen and fourteen the same as key rods ten with one two three or four pennies added, and so The conducon throughout the numbers. tors and sections of insulating. material are preferably formed into a solid pile by any suitable fastening means The contacts made by the key rods 3 with thelayers of 0011- ducting material 49, 49 &c., energize the magnets 55, 55 &c. Armatures 56; 56'' &c., are pivotally mounted 1n'fr'ames57 above these magnets, said armatures carrying segmental Tack sections 11 which mesh with pimons-lQ of. the registering or recording devices 18?. After thecircuit is broken. releasing the armatui'es, they are returned to the normal position by means of springs 58.

In Fig. 30, I have illustrated a form of machine having slidable members which ef feet the operation of the recorders by an electric current; the circuit being made and broken'by spring contacts carried by the slidable members and said members being identical with the arrangement of the machine shown in Figs; 1, 2 and 3.

Theracks 11 of the machine shown .in' Figs. 1, 2- and 3. are replaced by the extensions 11 carrying contacts 62. These extensions may be insulated from the balance of machine by any means forming a connection between them and the slidable members 6.
